DERRY — Six fire departments battled a two-alarm fire at the Sunview Condominium complex off Tsiennetto Road Tuesday evening.
The residents were not home at the time the fire broke out, according to Derry Battalion Chief Michael Gagnon.
Three adults were displaced as a result of the fire. They were being helped by the American Red Cross. The other units were not damaged.
The fire was reported around 6:15 p.m.
The fire was contained to the third floor of the four-story building, Gagnon said. There was heavy smoke and flames were shooting out of the third-story window.
"We had a full structure fire response," he said.
A dog was rescued from the fire, Gagnon said.
One firefighter sustained a minor hand injury, he said.
Derry had three engines, one fire truck and one ambulance at the scene and mutual aid was provided by Chester, Auburn, Windham, Londonderry and Manchester.
Firefighters sprayed water and foam onto the second floor. Other firefighters used tools to tear apart the interior to better extinguish the fire.
"The cause is still under investigation," Gagnon said.
About a dozen neighbors and other curious residents gathered to watch the blaze.
"We saw the flames coming from the top," neighbor Denise Dimambro said.
She said she heard beeping before seeing the flames.
Scott Montgomery, 49, said both the fire and firefighters seemed to appear instantly.
"Whatever happened, they addressed it pretty quickly," Montgomery said.
